Problems solved by technology

[0004] The speed limit of large loaded trucks on high speed is usually 60~80 kilometers. When a large loaded vehicle is rear-ended by a rear vehicle, especially by a truck, it will cause the vehicle to lose control quickly, and the vehicle will move forward rapidly, resulting in a series of accidents. occur

Embodiment 2

[0040] refer to image 3 with Figure 4 As shown, a first plate 9 that can move laterally is provided at the right side of the plate 3, the first plate 9 is parallel to the plate 3, and the first plate 9 also adopts Q235 material, with a thickness of 12mm, a plurality of rods 901 are welded at the left end of the first plate 9, and the rods 901 pass through the plate 3 to the left and are threaded to limit nuts 902, and the rods 901 A spring 903 with a wire diameter of 4 mm is sheathed on the top, and the spring 903 is pressed between the plate 3 and the first plate 9, and when the first plate 9 is subjected to a collision force, the spring 903 compresses the The spring 903 completes the energy absorption through the compression of the spring 903 .

Embodiment 3

[0042] refer to Figure 5 with Image 6 As shown, a foam board 333 is glued and fixed on the left side of the board 3. Under normal conditions, the foam board 333 is not in contact with the first board 9. When the first board moves , and compress the spring, before the spring is compressed to the limit, the first board contacts the foam board, and then the first board continues to move to the left to absorb energy until the foam board cannot be compressed, at this time the first board The force of the parts acts on the board, and the cooperation of the foam board and the spring realizes double energy absorption and improves the energy absorption effect.

Embodiment 4

[0044] refer to Figure 7 As shown, a soft contact plate 999 made of rubber is glued and fixed on the right side of the first plate 9, and the thickness of the contact plate 999 is 20mm.

Abstract

The invention discloses an auxiliary brake parking assembly based on vehicle passive safety, which includes pipe sleeves fixed at the front and rear sides of the vehicle frame, the pipe sleeve is fixed with the automobile frame by welding, and the pipe sleeve adopts a horizontal layout. A force rod is horizontally arranged in the pipe sleeve, and the force rod can slide laterally along the pipe sleeve. A plate is set between the right ends of the two force rods, and the force rod The right end of the right end passes through the plate and is welded and fixed. The plate is made of Q235 material with a thickness of 16mm~32mm. There are two bases welded on the bottom of the car beam. The two bases are left-right symmetrical. There are two vertically arranged first pipe sleeves welded between the seats, through which a vertical rod is equipped; this product can be installed on the main beam of a truck, and it can help brake when subjected to the impact of a rear vehicle. Reduce the forward impact speed of the vehicle and reduce the probability of serial accidents.

Description

technical field [0001] The invention relates to an auxiliary braking and parking assembly based on vehicle passive safety. Background technique [0002] Expressways are high-grade highways. According to the "Technical Standards for Highway Engineering" of the Ministry of Communications of the People's Republic of China, expressways refer to "highways that can adapt to the annual average day and night passenger car traffic volume of more than 25,000 vehicles, are exclusively used for high-speed driving in separate lanes, and all access and exit are controlled." Although countries have different names for expressways, they all refer to highways with more than 4 lanes (including), two-way separation, complete control of entrances and exits, and all interchanges. In addition, in many countries, direct arterial lines that partially control entrances and exits and not all use interchanges are also called expressways. [0003] Generally speaking, the expressway can adapt to a spe...
